Target applications

  • PSOC™ 4 HVPA:

    • 12-V lead-acid battery monitoring (intelligent battery sensors)

    • High-voltage battery current sensors

Use cases

  • As a 12-V automotive battery monitoring MCU: PSOC™ 4 HV PA features two high-precision delta-sigma ADCs to measure battery voltage, current, and temperature. The on-chip processor uses this information to calculate various parameters including state-of-charge and battery health. This information is reported to engine management and other computers via a serial LIN interface

PSOC™ 4 HV MS​

key features

  • Robust capacitive-sensing performance with very high SNR-enabling elegant automotive HMI

  • Connects directly to a 12-V battery supply and to the LIN/CXPI network

Target applications

  • Automotive body HMI (touch buttons/sliders/touchpads for steering wheels, door modules, overhead modules, etc.)

  • Liquid level and quality sensing

  • PTC heaters

Use cases

  • As several automotive HMI and body application MCUs: PSOC™ 4 HV MS is a mixed signal (MS) MCU with a 12-bit SAR ADC, 5th generation Multi-Sense Converter (MSC) block supporting capacitive sensing (CAPSENSE™), digital peripherals such as PWMs and serial communication interfaces along with a LIN interface with integrated PHY/CXPI, and a high-voltage subsystem to operate directly off the 12-V car battery
